A compression fitting for rigid or semi-rigid pipes comprising an internal element 11 onto which the pipe 12 is fitted and into which at least one circumferential groove 13 is machined and an external sleeve 20 usually cylindrical is positioned around the pipe and intended to be deformed by radial compression to push the wall of the pipe inside said groove. The external wall of the sleeve 20 bears a circumferential protruding bead 22 in line with its area which is found in line with the groove of the internal element with interposition of the wall of the pipe, so that the compression of the sleeve by action of a cylindrical pressing wall 30 acts on the bead to deform the sleeve with the purpose of pushing the wall of the pipe inside the groove of the internal element.

A compression fitting that obtains a rain tight fit on electrical conduit. The compression fitting includes a tubular body having a threaded forward end for connection to a panel and a threaded rearward end for connection to a conduit. A standard lock nut and seal ring, or, alternately, a snap ring and a seal ring are used on the forward end for obtaining a rain tight fit of the forward end with a panel or junction box. A compression nut, compression ring, and two seal rings are used on the rearward end to secure a conduit thereto in a rain tight fit. A first seal ring is constructed of plastic and includes a V-shaped outer periphery. A second seal ring is typically constructed of a deformable metal such as aluminum and includes a V-shaped inner periphery. The rearward end of the tubular body includes a seat shaped to accept the second seal ring. Tightening the compression ring onto the tubular member forces the compression ring to compress the first and second seal rings against the seat in the rearward end of the tubular body. The adjacent surfaces of the V-shaped outer periphery of the first seal ring, the V-shaped inner periphery of the second seal ring, and the surface of the seat compress flush against each other and form a rain tight seal. The compression fitting of the present invention creates a secure rain tight seal that overcomes the shortcomings of prior art compression fittings for conduit, which typically feature a split ring arrangement for sealing the conduit against the fitting.
